This invention relates to automatic winding machines, and has for its object to provide a machine of this description which, in a continuous operation, conducts bobbins, which have been placed in a magazine, to the spindles of the winding machine, holds them in position, carries out the winding automatically and after the winding operation automatically ejects the bobbins, and cuts off short the ejected bobbins and passes them in orderly disposal to a suitable conveying means, whilst empty bobbins are continuously being fed automatically from the magazine and secured in position for continuation of the winding process, without it being necessary in the course of this continuous operation to perform any actuations by hand. In addition to the ordered and fully automatic winding of the bobbins it is ensured by the machine according to the invention that even the finest yarns, such as artificial silk, can be wound on this machine.

The invention is illustrated by way of example in the accompanying drawings, in which Fig. 1 is an elevational side view of the machine according to the invention.

l represents the bed of the machine on which is mounted a frame 2. In this frame is a gear box 3 (Fig. 2) which contains any suitable conventional type of mechanism (not shown) for driving, from off a main shaft 2|, one or more spindles 4, and for reciprocating and rotating one or more thread guide rods 5. The bobbin spindles 4 and the thread guide rods 5 are conducted out of the gear box at the front.

From the upright frame 2 there extends a horizontal frame 6, which projects forwardly of the machine and carries in axially shiftable fashion in a suitable bearing 8, corresponding to the number of spindles 4 projecting from the gear box, the bobbin pressers 1 borne by shafts 9. Each shaft 9 is conducted out of the bearing 8 in opposite direction to the supporting point for the bobbin [0, and is furnished at a distance from the bearing 8 with a thread I l, on to which there is screwed a milled nut I2. In the space between the nut l2 and the bearing 8 there engages a stud l3 on a pivoted fork l4, which is mounted on a shaft I5. This shaft I5 is rotatably mounted in suitable bearings l6 secured to the frame 6. The studs l3 form the ends of a rod ll passing through the ends of the fork l4 and project out of the fork M on either side for engagement behind the nut l2. The width of the fork 4 and the length of the control rod I! guided by the fork are such that the studs I3 are capable of engaging in two bobbin pressers 1. If the fork l4 with its studs I3 is rocked outwards, the shaft 9 of the presser 1 will also be moved in the outward direction and the head l8 of the bobbin presser will be moved out of engagement with the bobbin I0. The return of the presser 1 into the position in which it is pressed against a bobbin ll] takes place by means of a spring l9 (Fig. 15), which is disposed within the bearing 8 about the shaft 9 of the presser and bears on the one hand against a shoulder 9 on the rod 9 and on the other hand against the end face 20 of the bearing 8.

Each of the spindles 4 has a head 22 which is provided with a mandrel for engagement in the bobbin Ill. The spindle 4 is not axially shiftable. The thread guide rod 5, which projects out of the gear box 3 between each two spindles, and somewhat above the center line of the spindles, is furnished on the part projecting out of the gear box with a thread 23 extending almost up to the long side bearing 24, in which the thread guide rod 5 is mounted to be axially shiftable and rotatable and which is mounted on the frame 6. Each thread guide rod 5 receives from suitable mechanism within the gear box both a rotary and a reciprocative motion.

On each thread guide rod 5 there is slidably arranged a thread guide support 25, which encompasses the thread guide rod 5 by means of a sliding bush 26. This bush 23 is open at the one end and at this point engages with a die 21 furnished with a similar thread, which die, by means of an angularly disposed arm 28, is

mounted by the shaft 29 on the body of the thread guide support and is held in position by two guide members 30. The die 2'! surrounds by means of an elongated aperture 3| a guide rod 32, which ensures the upright position of the body of the thread guide support 25. On the body of the thread guide support there are provided to the right and the left two projectory thread eyelets 33, 33 (Fig. 16), which extend over the positioned bobbins l and allow the thread to run on to the bobbin during the winding operation.

The thread guide support 25 which is held in engagement with the threaded portion 23 of the thread guide rod by the threaded die 21 is longitudinally shifted, by the rotary motion of the rod 5, against the action of a spring 34 which bears at one end against the body of the thread guide support 25 and at its opposite end, within the bearing 24, against an abutment 5 on the thread guide rod 5.

Upon the advance of the thread guide support 25 out of an initial position in the vicinity of the gear box 3 it, in the position indicated in the dash-dotted lines of Fig. 15, has moved into engagement with the stop 35 on the end of a rod 39. This rod is shiftable in abutments 36, 31 on the bearing 24 and carries, in the part thereof projecting beyond the abutment 31, a tup 38 which is adjustable on the rod 39 beyond the abutment 31 and can be maintained in any adjusted position thereon by a winged nut 40. The tup 38 engages with a guide stud 33 in a fork 4|, the main portion of the tup bearing against the fork. This fork is pivotally mounted upon a stud 42 located at the bottom of the bearing 24 in the abutments 42 thereon. With the thread guide support 25 engaging the stop 35 as shown in the dash-dotted line of Fig. 15, the tup 38 on the rod 39 will have moved the fork 4| into the dash-dotted position shown in this figure. When now the thread guide support 25 is moved away from the stop 35 thereupon the fork 4| will be returned to its initial position, as shown in the full lines of Fig. 15, by a spring 4| one end of which is secured to the fork and the other to the abutment 36.

The guide rod 32 for the thread guide support 25 is borne at its opposite ends by angle levers 44 which are secured to the rod by set screws 45 (Figs. 1, 15). These angle levers at the fore end of each guide rod 32 are pivotally mounted on arms 46 which extend from the fixed bearings 24. At the opposite or rear end of each guide rod the angle levers are pivoted directly to the fore end of the gear box 3. All the guide rods 32 for all the thread guide supports 25 are equipped with these angle levers 44, and for turning all the angle levers 44 for all the rods 32 there is provided a linkage 4! through which force may be directed for rocking the angle levers in reverse directions. When the rocking motion is in a clockwise direction, as viewed in Fig. 2, the guide rods 32 will be moved upwardly whereby threaded engagement between the threaded die 2'! of each thread guide support 25 and the thread guide rods 5 will be broken, whereupon the spring 34, which, due to the progressive movement of the thread guide support 25 during the winding has become compressed, is free to return the thread guide support 25 back to its initial position of winding, the return movement continuing until the thread guide support strikes a stop 48 adjustably mounted on the rod 32. If now the moving force on the linkage 41 be such as to move the angle levers in a reverse or anti-clockwise direction, as shown in Fig. 2, thereupon the rods 32 will be moved down to again complete threaded engagement between the dies 21 of the thread guide supports 25 and the thread guide rods 5 for continuing the winding operation.

During the winding operation the fork 4| is in a position shown in the full lines of Fig. 15 and forms a latch for holding latched in place a stud 43 on a control lever arm 49. This control lever as will presently be explained, is a spring activated lever, and when the stud 43 is released by shift in the position of the fork 4|, then the arm 49 will be released to turn, after which the arm may be returned to its original latched position. The lever arm 49, and in fact the whole control lever, of which this arm forms a component part, has a rocking movement as the arm is released from and returned to its latched engagement with the fork 4|. The lever arm 49 is fixed to a rotary shaft 53 at one end of this shaft. Fixed, also, to the shaft 53 is an arm 41 to the end of which the linkage 41 is pivotally secured. When the lever 49 is in its latched position with the fork 4|, it will then have moved down the guide rods 32 and thereby will hold the thread guide supports 25 with associated dies 21 in threaded engagement with the thread guide rods 23. On the release of the lever from its latched engagement with the fork 4! its consequent turning, following its release, will through these same parts raise the guide rods 32 and thereby move the thread guide supports into disengagement with the thread guide rods 5.

Fixed to the end of the rod 53, opposite that end to which the lever arm 49 is fixed, is a lever arm 49' in direct opposing relation to the lever arm 49, the two arms combining to form the complete control lever. At its end the arm 49' is connected through a folding joint 50 to a twoarmed lever which lies in extension of the control lever to which it is attached, and is pivotally supported on the bed of the machine by mounting on a bearing 52. When the arm 49 of the control lever is released from its latched engagement with the fork 4| this arm will move upwardly and the arm 49' of the complete control lever will move downwardly. The inner arm of the lever 5| will consequently move downwardly, and its outer arm, beyond the point of its pivotal attachment, will move upwardly. On the return of the control lever to its initial latched position, or, in other words the latching of its arm 49 to the fork 4|, a reverse movement of the levers takes place. These rocking movements of the levers are availed of to effect various operations, and reference will first be made to that for the control of a stop mechanism (not shown) which stops or starts the mechanism which drives the spindles 4 and actuates the thread guide rods 5.

Arranged in a position adjacent to and above the inner arm of the lever 5| is a rock shaft 62, the reverse turning of which controls the stop mechanism above referred to. Fixed to this shaft 62 is an arm 63 to which is pivoted a link 63 which has pivotal connection with the inner arm of the lever 5| by a pin 5| on the arm of the lever entering a slot 63" in the link 63'. Fixed, also, to the rock shaft 62 is an arm 62' which is under the action of a tension spring 64 interposed between the arm and a case 55 for mechanism later to be referred to. The normal action of the spring working through the arm 62 is to turn the rock shaft 62 in a clockwise direction, as viewed in Fig. 2 when the rod will actuate the stop mechanism to stop the drives for the spindles and thread guides. A reverse turning of the arm 62', with tensioned extension of the spring 64, will turn the rock shaft 62 in a reverse or anti-clockwise direction, as viewed in Fig. 2, whereupon the stop mechanism will be actuated to start or throw the drives for the spindles and thread guides into operation. In the latched position of the control lever, which is the position shown in Fig. 2, where the lever 49 is in latched engagement with the fork 4|, the arm 49 of the control lever Will have been turned up as will the inner arm of the lever 5|. In consequence through the link 63 and arm 63 the rock shaft 62 will have been turned in an anticlockwise direction in an amount sufficient, acting through the stop mechanism, to throw the drives for the spindles and thread guides into action. At such time the spring 64 will be extended and thereby tensioned. When now the control lever is released from its latched engagement, or, in other words, when its arm 49 is released from latched engagement with the fork 4|, thereupon the lever arm 49 and the inner arm of the lever 5| will turn downwardly thereby allowing the spring 64 through the arm 62 to move the rock shaft 62 in a clockwise direction and actuate the stop mechanism to stop the drives for the spindles and thread guides.

The control lever, which includes the lever arms 49 and 49', and the lever 5| are under the tensional control of a spring 54. One end of this spring is secured :to the end of the outer arm of the lever 5|. The opposite end of the spring is secured to the case 55. When the control lever 'gagement with the fork 4|.

is in latched engagement with the fork 4|, the end of the lever 5| to which the spring 54 is attached, will have been moved down thereby tensioning the spring 54. Upon detaching or unlatching the control lever from the fork 4| the spring 54, exerting force to draw upwardly the end of the lever 5|, will, through the line of levers, displace the arm 49 of the control lever upwardly away from its latched connection with the fork 4|, and incidentally will rock the shaft 53 to which the control lever is secured in a clockwise direction. Thus it will be seen that the line of levers when latched are under the tensional control of the spring 54 which causes their displacement as explained when unlatched from the fork 4|. If now the end of the lever 5| be depressed a reverse action of the levers will take place, the control lever will again become latched, and the shaft 53 to which the control lever is fixed will be turned in an anti-clockwise direction.

Located above the end of the lever 5| within the case 55 is a clutch mechanism which is activated by the lever 5| when the arm 49 of the control lever is released from its latched engagement with the fork 4|, and which clutch mechanism is thrown out or disengaged when the arm 49 of the control lever is returned to its latched engagement with the fork 4|. The clutch mechanism includes a continuously rotating worm wheel 58 which is driven by a worm 59 on a shaft 60 turned in any suitable manner in the operation of the machine. The worm wheel 58 is journalled to turn on the casing 55 and carries on its under side one or more pins 51. Beneath the wheel 58 is located a freely rotatable cam disk 56 which bears a pin 56'. This pin is adapted to have clutch engagement with one of the pins 51 on the continuously rotating wheel 58 when the cam disk is lifted, whereupon during the continuance of such engagement the cam disk 56 will be rotated by the wheel 58. The cam disk is lifted by the outer lever arm of the lever 5| as this arm turns upwardly on the release of the arm 49 of the control lever from its latched en- The outer arm of the lever 5| has secured to it a finger 56" which extends laterally beneath the cam disk 56 and acts to lift the disk as the lever arm becomes lifted. The cam disk is held against rotation by a stop 6| on the body of the frame of the machine which enters a slot 6| in the edge of the disk. When the stop is in this slot the cam disk cannot be turned. The cam disk can be turned when the lever arm has lifted it above the plane of the stop 6| at which time the disk will be thrown into clutch engagement with the rotating wheel 58 and be turned thereby. The action is one in which the cam disk 56 is made to have only a single complete revolution after the throwing in of the clutch, disengagement or throwing out of the clutch being effected at the completion of such revolution. To this end the cam disk is formed on the under side thereof with a projection or cam 56*, which, when the cam disk is approaching the end of its single revolution will enter between the disk and the finger 56" on the forward arm of the lever 5| and depress this arm, thereby turning the lever 5| and returning the arm 49 of the control lever again into latched engagement with the fork 4|. The complete revolution of the cam disk 56 will now have brought the slot 6| in the edge of the disk into alignment with the stop 6| on the frame, whereupon the cam disk 56 will be thrown out of clutch engagement with the wheel 58 by means of an arm 69. This arm is pivoted to the casing 55 and the end of the arm has drawing engagement with the top of the cam disk 56 by means of a spring 10, one end of which is connected to the end of the lever 69, and the other to the fore end of the lever 5|.

The cam disk 56 when rotated by the wheel 58, on being thrown into clutch engagement therewith, brings about certain operative effects. The disk is provided on the top with a cam H which is fixed to the disk. Against this cam, as shown in Fig. 1, there bears by means of the wheel 12 a lever 13 which rocks the forks I4 on the shaft I5 by way of connections 14, 15 and 16 (Fig. 1), thus causing the bobbin pressers 1 to be withdrawn in the bearings 8 so that the wound bobbins II! will fall away from the spindles. Owing to the form of the cam H the bobbin pressers remain in the withdrawn position until the empty bobbins taken from the magazine, as will later be explained, have been brought forward by the carriage 6B, and it is not until the carriage has moved the empty bobbins into position to be clamped between the bobbin pressers 1 and the heads of the spindles that the cam 1I releases the forks I4 so that, under the action of the springs I9 built into the bearings 20, the heads I8 of the bobbin pressers are able to move against the new bobbins and press them against the mandreled heads 22 of the spindles.

The cam disk 56 has, also, on its under side a crank pin 65 which engages in a slot in a pivotally mounted lever 66 even in the lifted or clutch forming position of the disk. This lever 66 is mounted on a journal 66 on the bed I. A longitudinal slot in the lever 66 is engaged by a stud 61 located on the under side of the carriage 58. Through these connections the carriage 68 will be moved with a long sweeep to the left, as viewed in Fig. 2, from an initial position beneath the magazines I44, presently to be referred to, containing empty bobbins, to a position beneath the spindles and thence will be moved back to its initial position.

During its movement the carriage performs various operations, the essential one of which is to receive empty bobbins from the magazines I44, carry them, and place them on the spindles in position for Winding in replacement of the wound bobbins which have dropped out. The magazines I 44 correspond in number to the number of spindles 4. As indicated in Fig. 2, the magazines I44 are at the right of the spindles. The magazines have two guides I45, I46 (Fig. 1) having the empty bobbins I43 disposed between them. At the lower end of the guides I45, I46 there is located a laterally shiftable closure slide I41, which extends in the form of a throughgoing plate below all the magazines I44. Laterally of each magazine there is provided in the said plate an ejection opening I48, which is covered by an angular gripper plate I49, the angular opening being directed towards the appertaining magazine. The length of the gripper plate I49 is such that it can be moved between the guides I 45, I46 into the stacked empty bobbins. The opening in the gripper is so dimensioned that it corresponds to the largest diameter or, in the case of shaped bobbins, to the distance between two bobbins. The empty bobbins I43 are held in position in the magazines I44 by the slide I41 effecting closure in the position of rest. The

member I41 is moved by means of a stud I50 on the carriage 68 moving below the closure memher. under the action of a spring I5I into its normal position, which is that shown in Fig. 3. The spring I5I is attached to a post I52 secured to the machine frame. The slide I41 is guided in corresponding guides on the frame of the machine.

The carriage 68 adapted to move below the closure slide I41 comprises a main frame I53 on the lower side of which there is located the stud 61 previously referred to, which engages the rocking lever 66. On the upper side of this frame I53 there are four bearings I54 fitted with a spaced set of cross rods I54 which engage in oblique slots I55 in the sides of a shiftable frame I56. This frame I56 rests normally by its own weight on the cross rods I54 with the ends of the rods normally contained at the top ends of the slots. The frame I56 possesses recesses I51 corresponding to the spacing between th magazines I44, and the spindles 4, which recesses are such that in each case there may rest therein the ends of the empty bobbins dropped from out of the magazine. On this frame I56 of the carriage is located a stud H56 which is brought into engagement with the gripper plate I49 in the operation of the machine. After the completion of one winding operation and preliminary to the delivery of a new set of empty bobbins to the winding spindles the carriage is moved to the right as shown in Fig. 2 by the lever 66, whereupon the stud I56 on the carriage will be brought into engagement with the gripper plate I49 borne by the slide I41 whereupon the gripper plates will grip into the stacked empty bobbins and at the same time the slide I41 will be moved by the width of any empty bobbin towards the right, whereupon the openings I48 in the slide below the stacked bobbins will allow the bottom bobbins to fall out of the magazine, while by reason of the grippers I49 the bobbins situated above are retained. The bottom lay of empty bobbins thus released to fall out drop as shown in Fig. 4 into the recesses I51 in the frame I56 of the carriage. The carriage now having received its complement of empty bobbins performs a long rocking movement to the left carrying the empty bobbins. An intermediate position is shown in Fig. 5 in which the carriage has already moved somewhat away from the magazines I44. Upon this initiated movement of the carriage the stud I50 has released the closure slide I41 which, under the action of the spring I5I returns to its normal position of closure. Thus the closure slide I41 will close the bottoms of the magazines and the gripper plates will be withdrawn from the magazines. The empty bobbins I43 in the magazines will then follow up and be held in the magazines by the plate I41 then occupying a closed position. The carriage, rocked by the lever 66, continues its movement to the left until it reaches an extreme left position as shown in the dash-dotted lines in Fig. 5 where the carriage is shown immediately below the spindles, and the unwound bobbins borne by the carriage in vertical alignment with the spindles. Shortly before reaching this extreme position, the frame I56 movably mounted on the carriage frame as it is, will come into contact with a fixed stop I66 on the bed of the machine whereupon the frame I56, upon the further advance of the frame I53 of the carriage cannot be shifted further to the left on account of the stop, consequently, under the action of the oblique slot guides I55 in the sides After displacement the member I41 returns of the carriage frame I53, the frame I56 is lifted vertically and the empty bobbins carried by it are lifted to the levels of the spindles 4, and held in this position until the action of the cam drive 1I through connections 12, 13, 14, 15 and 16 has released the bobbin pressers I to hold the unwound bobbins thus positioned in readiness for winding when the spindle drive next starts.

During the movement of the carriage 68 to the left, before it registers the limit of its movement and the bobbins carried by it are lifted into placement for winding, further operations take place through elements activated and controlled by the moving carriage. These further operations include the positioning of the trailing thread, its holding, and cutting. In this connection it will be explained that during the progress of the carriage 68 to the left the wound bobbins, already released from the spindles by the withdrawal of the presser 1 through action of the cam 1|, have fallen to lie within the compartments 19 of an intercepting container 11. The wound bobbins have but a short fall into this intercepting container which lies immediately below the plane of movement of the carriage 68. The container 11 comprises single channel-like compartments corresponding in their location to the disposal of the spindles (Fig. 2), the partitions between the single compartments preferably consisting of sheet metal ribs 18 bent into V-shaped form so that the wound bobbins falling down from the spindles are each able to enter in reliable fashion a corresponding compartment 19 of the container. It is the thread left trailing from the wound bobbins lying within the compartment 19 that is positioned, held, and cut at points lying below the spindles, and below the points where the threads are being held in order that the trailing threads may not only be cut, but the portions of the trailing threads lying above the cuts will continue to be so held so that they will extend over the spindle heads where they may be clamped between the head ends of the empty bobbins applied to the spindles and the mandreled heads of the spindles, in order that the threads thus trapped may wind upon the bobbins when the wind is continued.

The carriage 68 during its reciprocatory movement is guided in part at the front by its bottom plate resting in the guide I59 (Fig. 18). This guide extends along the path traversed by the carriage. On the opposite side the carriage is guided by a long blade I58 laterally projecting from the bottom of the carriage, and which engages in a grooved slideway I 59 This slideway I58 extends along the under side of the magazines and terminates at a point between the magazines and the space beneath the spindles. It does not extend under the spindles. Accordingly, when the carriage has moved to a point beneath the spindles the main portion of the blade I58 will lie forward of the slideway I 59 and present an edge I 58 over which the trailing thread may extend. The forward end of the blade I58 is provided with a bevel I68. Accordingly, when the carriage 68 moves forward to the left, to bring the fresh supply of empty bobbins carried by it under the spindles, the beveled end I68 of the blade will strike the trailing threads connecting as they do with the wound bobbins already deposited to lie in the compartments 19, and as the movement of the blade continues will move the threads aside so that they will trail over the edge I 58' of the blade I58. The trailing threads thus initially positioned are further positioned and held by means of shiftable grippers or clamps I61 which not only position, but, also, hold the threads tightly clamped at points lying immediately below the heads of the spindles so that the threads thus held may be clamped between the heads of the freshly inserted bobbins and the mandreled heads of the spindles when the bobbin pressers 1: are released to hold the freshly inserted bobbins. Associated with the clamping means for the thread are shears 85. These shears are disposed below the thread holding clamps in order that they may cut the thread at points lying below the clamps so that after the cutting the threads may continue to be held by the clamps as aforesaid. Both the shiftable grippers I61 and the shears 85 are actuated by the moving carriage 68. To this end there is mounted in suitable manner upon the frame of the machine a horizontally extending fixed plate I69. This plate lies above the plane of the blade I58 and in position where the front edge I69 of the plate will lie just inwardly removed from a vertical plane in which lies the edge I58 of the blade I58. Mounted upon the top of this plate are the shiftable grippers I61. These grippers I61 consist of a pair of opposing gripper portions which extend beyond the edge I69 of the plate I69, and of which one pair of gripper portions is assigned to the gripping and holding of each thread, there accordingly being four pairs of gripper portions in all. One each of the pairs of gripper portions assigned to each thread is fixed to a bar I16, the second of each pair of gripper portions is fixed to a bar I80. The bar I16 is held by claws I11 to be longitudinally shiftable along the surface of the plate I69 and to project beyond the end of the plate I69 at the end directed towards the magazines where the bar is squared for the purpose of forming a suitable abutment face. The opposite or fore end of the bar I16 has an angularly turned end I16. Interposed between this end and a post on the plate I69 is a spring I83. In pivotal engagement with the outer end of this turned end I16 is a rocking lever I18 pivoted at the point I18 to the fore end of the plate I 69. The free end of the rocking lever is pivotally connected to the bar I which extends along the top face of the plate I68 between it and the bar I16. In consequence if the upper gripper bar I16 be moved by force applied to its end abutting face the lower grip- .per bar I88 by way of the rocking lever I18 will be moved along the plate I69 in an opposite direction. In this way the two portions of each pair of grippers I61 are moved together and meet in the position where they engage and hold the thread, already initially positioned by the advancing blade I58, vertically below a spindle axis.

It is the moving carriage 68 which applies this moving force to the end abutting face of the bar I16. When the carriage has become so far advanced that the blade I58 carried by it has moved the trailing threads I28 into position to be gripped and held by the grippers I61 thereupon a lever I58 on the carriage will be brought into engagement with the end of the bar I16 for moving it. For the purpose of obtaining a more general movement and to permit of a certain resiliency and compensate for further advance movement of the carriage after the grippers have been brought into engagement with the threads this lever is pivotally mounted in a one directional fashion at I8I on the carriage and at the other end is held in a state of tension by a spring I82. After the advance movement of the carriage has caused the grippers to engage and hold the threads the retraction of the carriage will allow the grippers to resume their normal position, this being effected by means of the spring I83 which causes the rods carrying the gripping parts to resume their normal positions of rest.

The shears 85, previously referred to, which cut the threads when held by the grippers, are disposed on the under side of the plate I69, there being shears for each thread to be out. One blade of each of the shears is rigidly secured to the plate I69 in an oblique position. The second blade of each of the shears is pivoted at the point III! to its companion fixed blade on the plate I69. At their opposite free ends these movable blades of the shears each has in it a slot in which lies a pin I'II borne by a rod I12. This rod is longitudinally shiftable within ways I73 on the under side of the plate I69, and the end of the rod I12 extends beyond the end of the plate I59 in a direction towards the magazines. The rod I12 is held in a normally retracted position for holding the blades of the shears open by means of a spring I14, one end of which is secured to an offset I I from one of the ways I13, and the other end of the spring is afiixed to an arm I'I3 on the rod I12. Upon the advance of the carriage 68 and abutment I58 on the end thereof, which is secured to the carriage and can be adjusted to a certain length by suitable provision of set screws, strikes against the end of the rod I12 and thereby closes the pivotal blades of the shears enabling them to then cut the threads. In this connection it is to be observed that the relative position of the abutment I58 which activates the shears, in relation of the abutment I58 which activates the thread grippers, is such that the grippers will be actuated to grip the thread before the action of the shears takes place, the two operations following in relative sequence as the carriage 68 advances. The advancing movement of the carriage accordingly occurs in such manner that the blade I58 will move the trailing threads from the fallen bobbins to the edge of the plate I69 which carries the thread grippers and shears. When thus initially positioned the threads are engaged by the grippers which close under the action of the lever I58 The grippers accordingly hold the thread until, upon the further advance of the carriage 68, the shears will close under the action of the abutment I58 After the cutting of the threads the grippers will still continue to hold these portions of the threads then positioned to extend over the spindle heads all the time while the carriage is supplying empty bobbins I43 to replenish the spindles, and will continue to hold the threads until through release of the presser bars I the positioned bobbins have been clamped in place between the spindle heads and presser bars I, thus clamping the threads between the heads of the spindles and the heads of the bobbins whereupon the threads will wind upon the bobbins when the wind is continued. In fact the grippers are not opened, and the same may be said of the shears, until the carriage 88 moves back in the direction of the magazines under the action of the rocking lever 66 when the shears are first allowed to open under the action of the spring I14, the abutment I58 then being released, and then on the release of the lever I53 the spring I83 will restore the grippers to their normal open positions of rest.

As previously explained the wound bobbins are released from the spindles to lie in the compartment I9 of the container 11, and the dwell of the wound bobbins in these compartments continues during the holding and cutting of the trailing threads and until the retraction of the carriage 68, when the wound bobbins are released from the compartments, as will presently be explained. Each of the compartments I9 is formed at its forward end with an inclined face 84 against which the end of the wound bobbin strikes when falling down from the spindle so that the bobbin during its fall into the inter cepting container or compartment is tilted somewhat in relation to the spindle and thrown forward in the compartment into which it falls. This arrangement is made so that the thread wound upon the bobbin in a few layers at the lower or head end thereof at the termination of the winding operation owing to the return movement of the thread guide 25 as previously explained, will so lie that it will be struck by the blade I58 on the moving carriage and so positioned that it may be held by the grippers I61, and cut by the shears 85, At the same time, owing to the small space between the wound bobbin held in the intercepting container TI and the shears 85, there will be but a small end of thread on the bobbin subsequently expelled from the container which is advantageous inasmuch as long loose ends of thread always give rise to entanglements and cause the loosening of further layers of thread.

After completing its movement to the right the carriage returns to its initial starting position beneath the magazines. During this return movement of the carriage various operations are effected by it including the release of the holding means I61 and shears 85 and their restoration to their normal open positions of rest, as previously explained. Another operation is effected by the returning carriage and that is to release the wound bobbins from the compartments I9 in order that they may fall out of these compartments into a receptacle, or be otherwise taken care of, as will later be explained. The wound bobbins in the compartments 19 are held therein by strips 86 which form the bottoms of the compartments. These strips are united in a frame which is arranged to slide laterally beneath the container I1 and its compartments 19. The strips are mounted in the frame at approximately equal distances 8| apart. In consequence as the louvre-like frame is moved backward and forward beneath the container the strips 80 will either close all the compartments 19 or, by lateral displacement of the frame, the spaces SI between the strips will be aligned below the openings in the compartments 19 so that the bobbins are able to fall out. The strips 893 are held in position to normally close the bottom of the compartments I9, and hold therein the wound bobbins after they have been released to fall from the spindles, by means of a tension spring I64 interposed between the end of the framed strips and the frame of the machine. The strips are opened, so that the wound bobbins in the compartments I9 may fall out, by means of the carriage 68 and is effected through various elements which include a rod 82 secured to the end of the framed strips 80 with extension along This rod is made The rod is provided with a head 83 having a bevelled fore edge 83, a back edge 83", and a slot 83 on its under side. The head bearing end of the rod is urged to have an upward displacement by means of a spring 82" on the bed of the machine engaging the under side of the rod. Associated with the head 83 is a pawl I6I eccentrically pivoted by a pin I63 to the frame I of the machine so that the pawl will occupy by gravity a normally engaging position. The pawl is provided with an upright finger I62 by which it may be turned into a disengaging position. Arranged forward of the head 83 on the frame I of the machine is a pin abutment I60. The normal position of the head and pawl are as shown in Fig. where the strips 80, subjected to the tension of the spring I64, are shown closing the compartments I9.

As the lever 66 approaches the end of its return movement, after supplying the spindles with fresh unwound bobbins, it engages the back edge 83" of the head 83 thereby moving the head into engagement with the pin abutment I60. As the head of the rod 82 becomes thus moved the strips 80, normally closing the compartment 19, will be shifted into an open position as shown in Fig. 3. Engagement of the head with the pin abutment I tends to depress the head whereupon the lever 66 will pass up over the back edge 83" of the head and ride over the head than coming to a position of rest, substantially as shown in Fig. 3. At this same time the strips 89 will continue to be held open, inasmuch as the pawl I6I will have engaged the slot 83" in the under side of the head, whereby the head becomes locked between the pawl and the abut ment 560, preventing its retraction by the spring IE4. When the lever 66 is again activated by the clutch mechanism its initial movement is one in the direction of the arm I62 of the pawl, engaging this arm, and rocking the pawl as in Fig. 4, to disengage it from the head 83, thereby releasing the head, whereupon the strips will be drawn to a closed position by the spring I64 closing the compartments I9. The lever 66 will then take a long sweep to the left during which time the strips 80 will be occupying their closed positions, and the head 83 and associated pawl I6I their normal positions of rest, as shown in Fig, 5.

A modification of the intercepting container for orderly discharge of the wound bobbins can be carried out on the lines illustrated in Figs. '7, 8 and 9. In Fig. 7, in contradistinction to the horizontal disposal of the bottom 80 in conjunction with sloped guide faces 84 (Fig. 1), the sloped guide faces 89 and the closure slides 90 are disposed on one inclined plane. In this way an improvement in face of the arrangement previously described consists in the fact that the falling bobbin moves in reliable fashion with its lower end into the immediate vicinity of the machine gear independently of the length of the bobbin, so that it is always ensured that the thread drawn upon during the fall of the bobbin will always move to within reach of the shears 85, even in the case of dissimilarity in the length of the bobbins. The slide 90 of each single compartment is controlled in a frame, exactly in the manner as previously described.

A further embodiment is illustrated in Fig. 8, in which the bobbins fall into intercepting troughs 9i, the throughgoing bottoms 92 of which are inclined in relation to the spindle axis in the position of interception. These intercepting troughs are open at the ends directed towards the bed I of the machine, whilst at the opposite ends they are pivotally mounted at 93 on the frame 6. In the position of interception, which is indicated in Fig. 8 in dash-dotted lines, the intercepting trough 9! is held by a roll 94, which is mounted vertically to a lever 96 pivotally mounted at 95. The fulcrum 95 is constituted by a shaft on a supporting arm 91 mounted on the frame 6. The roll 94, which would be capable of oscillatory motion by way of the pivoted lever 96, is held in position by a two-armed lever 98, which is pivotally mounted on the bearing 99, and the free arm of which is pivoted to a tie rod I00, so that any pressure or tension exerted on this tie rod causes a rocking movement on the part of the two-armed lever 98, so that the intercepting trough 9| is capable of rocking upwards and downwards under its own weight about the pivot 93. The wound bobbin I0 falling oiT the spindle 4 is caught in the intercepting trough 9I and owing to the slope slides therein towards the open end. Opposite to the open end of the trough 9i there is mounted on the frame 6 an arcuate stop plate IOI forming part of a circle having its centre coincident with the pivot 93. This stop plate IIlI holds the bobbin I0 in the intercepting trough 9i, so that the bobbin is properly retained in the position indicated in dash-dotted lines during the severing of the thread.

If a control movement of the connecting rod I00 derived from the cam drive rocks the trough 9| out of its intercepting position after completion of the cutting operation, the bobbin I0, 0wing to the arcuate form of the stop plate IN, is held in the trough during the rocking of the same until in an ejection position shown in Fig. 8 a suitable aperture I02 in the plate IOI enables the bobbin I0 to slide out of the trough 9I. In place of the aperture I02 the stop plate IOI can also be so dimensioned that it terminates in front of the position in which the bobbin slides out. The bobbin I0 leaving the trough 9| now slides with its lower end in front into a conveying box I03, which is conveniently located on a sloped surface I04, so that the bobbins successively leaving the troughs are caused to assume an upright position side by side in the box I03. In this connection the arrangement may also be such that, as in the modified arrangement illustrated in Fig. 9, an even advance of the conveying box I03 on the sloped surface I04 is brought about during the successive discharge of the bobbins, so that an orderly disposal of the bobbins I0 one behind the other is obtained.

In spinning and weaving mills a usual mode of conveying weft and other bobbins makes use of a studded board, on which the wound bobbins having central passages are placed over studs or pins usually mounted on the board in four rows. Heretofore it has been necessary to place the bobbins on these boards by hand. As compared with boxes, in which the bobbins are situated loosely in superimposed or adjacent disposal, the boards have the advantage that they are more handy and they also enable the operator attending the loom to obtain immediately full knowledge with regard to a particular shade of colour, the quantity of yarn on hand and the nature of the yarn.

The combination of these advantages with those of the orderly discharge of the Wound bobbins from a winding machine in accordance with the invention is shown in the modification according to Fig. 9 and in the detailed views in Figs. 10 to 14.

As in Fig. 8, there is used also in this modification a pivotally mounted trough 9| suspended in similar fashion as at 93 and having the same form of rocking control, which latter, for the purpose of facilitating comprehension, has consequently been omitted from Fig. 9. There is likewise provided an arcuate stop plate IOI, this are being part of a circle having its centre at 93. At its bottom it possesses in place of the simple aperture I02 in the embodiment according to Fig. 8 a sleeve I85, so that the wound bob bin I leaving the intercepting trough 9I is guided in its movement until being taken over by the board I06 and the studs or pins I0'I mounted thereon.

Further, the intercepting troughs are not, as in the arrangement according to Fig. 8, disposed in accordance with the spacing of the spindles. At the bottom the single troughs, as shown in Fig. 10, are no longer separated by V-shaped partitions, but are so formed with the side-walls I08 in conjunction with the bottom that the bobbins falling into the same come to rest in a spacial disposal corresponding to the four rows on the studded board. Accordingly also in the example of the four-spindle machine four guide sleeves I are provided in conjunction with a thoroughgoing stop plate IN. The studded board I06 is fitted to slide loosely in the inclined frame I09, as shown in Figs. 9, 11, 12, 13, 14. Each board possesses at its end a stop plate II9 projecting at the bottom.

If the studded board is fitted in the frame I09, it slides, owing to the sloped position, into the frame I09 until the stop plate IIO moves into engagement with a toothed shaft I I I. The toothed shaft III is mounted to rotate below the frame I09 in bearings I I2, H3, and comprises a cylindrical roller portion, on which there are arranged in spiral distribution teeth II4 spaced axially to correspond to the distance between two rows of studs on the board I06. The distance spirally from one tooth II4 to the next is, as stated, equal to the spacing between two rows of studs and at an angle of rotation which is dependent on the extent of rotation of the control means for the shaft III. The shaft III is coupled to the trough, for example by means of a ratchet gear II5. On the trough 9| there is rigidly mounted a lever I I6, which participates in the rocking motion of the trough out of the intercepting position into the position of ejection. At the end of the lever II6 there is provided a connecting rod II1 which, as shown in Fig. 14, reciprocates a pivotally mounted lever I I8, which is made integral with the ratchet gear II5.

If the connecting rod II'I upon the upward movement of the trough 9| has a pull exerted thereon by the lever II6, an angular movement will be imparted to the shaft III by way of the ratchet gear H5. The first tooth II4 (Figs. 11, 12, 14) moves out of engagement with the stop plate I I0, and owing to the slope of the frame I09 the studded board slips forward until it is stopped by the next tooth after completion of the angular movement. Upon the subsequent rocking movement of the trough 9| into the position of discharge and under the pressure transmitted by the rod II! the ratchet II5 runs idly on the ratchet head of the shaft II I.

The emerging bobbin can accordingly be picked up in secured position of the studde board, and it is only the new upward rockmg movement of the intercepting trough into the new position of readiness that causes in the meantime an advance of the board. The studded board I06 accordingly has the bobbins applied successively thereto, and at the end it slides into a removal frame II9, from which it can readily be taken and conveyed to a desired point.

In order after one studded board has been filled to have a second board in readiness there is provided on the frame I09 a second frame I20, which in accordance with Figs. 11 and 13 attends to the advance of a replacement board. The replacement board IIlGa is held in the position of readiness by a locking lever I2I against its stop plate 011, which lever is rotatably mounted on the frame I09 about a stud I 22. At the free end of the double-armed lever I2I there is a running-on roll I23, which acted upon by the spring I24 controls the position of the board I06 to which the bobbins are being applied. If upon progressive downward movement of the first board I06 after the last row of bobbins has been applied the roller I23 is able to rock freely under the action of the spring I24, the lever I2I releases the stop II 0a of the second board I06a. The board I06a comes under control of the pressure lever I25, which is acted upon by the spring I26, into the position of readiness of the main frame I09, and with the stop plate H0 is now stopped by the first tooth I I4 on the shaft III with the first row below the ejection tubes I05.

The thread or yarn I28 drawn freely in the known manner from the spool I2'I is conducted by a guide I29 to a reversing wheel I30 (Figs. 1 and 2), which if necessary can be furnished as desired with thread-braking means of the conventional kind. From this reversing wheel I30 the thread I28 passes to a tensioning eye I3I mounted on a rod I32. This rod I32 is secured to a comb I33, which is pivotally mounted on a shaft I34 eccentrically to its centre of gravity. The shaft I34 in turn is secured at both ends by means of rocking levers I34a to a shaft I35, which is rotatably mounted in bearing I36 secured to the gear box 3. The bearings I36 form at the same time the bearings for a shaft I31, on which there are mounted cam levers I38. The shaft I31 receives by means of the connecting rod I39 an oscillatory motion from the eccentric drive I40, so that the cam levers I38 have a continuous oscillatory motion imparted to them. The rods I32 carrying the tension eyes I3I are held in their outermost position by a yoke I4I, which is secured to the frame and extends over all spindles, and this position is maintained by the pull of the thread I28 being wound. If a break in the thread occurs, the comb I33, owing to the eccentric nature thereof, and the rod I32, by reason of the eccentric location of the centre of gravity, have the tendency to approach the appertaining cam lever I38. During this powerful reciprocation of the cam lever I38 the comb I33 moves into engagement with the cam lever and receives a blow, which is transmitted to the shaft I34 and by way of the rocking levers I340; imparts a rocking motion to the shaft I35. This rocking motion can be availed of in desired fashion for disengaging the spindle drive.

It will first be assumed that the spindles are being driven and winding of the bobbins taking place. The thread guide rods 5 are being reciprocated and turned and the thread guide carriers 25 are being moved progressively outwardly by and upon these rods as they are turned. The arm 49 of the control lever will then be latched to the fork 4|, and the line of levers connecting therewith, including the arm 49' of the control lever and the lever 5 I, will be occupying positions where the shaft 53 will be turned to position where it, through the linkage 41, will be holding the thread guide carriers 25 in threaded engagement with the thread guide rods on which they are mounted; the stop actuating shaft 62 for the spindle and thread guide drive will then be occupying an engaging position to permit of the operation of these drives for the spindles and thread guides; the lever 5| will then be occupying a disengaged position with relation to the cam gear 56 of the clutch mechanism; the control for the bobbin presser mechanism will then be in an inactive position allowing the bobbin pressers to be in engagement with the bobbins being wound for holding them in place, the carriage 68 will then be in a position of rest beneath the magazines M4 in readiness to receive a fresh supply of unwound bobbins, and the strips 80 will then be occupying an open position with relation to the bottoms of the compartments 7!] into which the wound bobbins are adapted to fall when released.

When now the wind has been completed on the bobbins one of the thread guide carriers 25 will engage the stop 35. Thereupon the fork 4| will be tripped releasing the control lever, through release of its latched arm 49, and the position of this lever and the lever 5| will become changed under the tensional control of the spring 54. The first immediate action is to release the thread guide carriers from their threaded engagement with the thread guide rods effected by the reverse turning of the shaft 53 and intermediate connections. On the release of the thread guide carriers 25 from the thread guide rods the carriers will be returned to their initial positions by action of the compressed springs 34, when, on account of the continued rotation of the spindles before actual stoppage, the connecting threads will become disposed to connect with each bobbin at a point adjacent its head. The drives for the bobbins and thread guides will be stopped through reverse turning of the shaft 62. The lever 5| will activate the clutch mechanism whereupon on rotation of the cam gear 56 and cam H the mechanism controlling the bobbin pressers will release the wound bobbins. At this same time the carriage 68 will be moved to complete its movement to the right as shown in Fig. 2, thereby tripping the pawl |6| and permitting the strips 80 to close the bottoms of the compartments 7.) into which the wound bobbins are about to fall. This closure of the bottoms of the compartments 19 takes place before the wound bobbins are released through release of the mechanism which releases the bobbin pressers, the action of release being sufficiently retarded to permit of the closure of the compartments. By this same movement of the carriage to the right the gripper blades I49 will be moved into the magazines, and a single bottom lay of unwound bobbins released onto the carriage. Thereupon the carriage will be moved with a long sweep to the left into a position beneath the spindles whereupon the magazines will again become closed and the grippers I49 released from the magazines. On its way to the position beneath the spindles the carriage will, through the blade I58 carried by it, position the trailing thread connecting with the wound bobbins, al-

ready deposited in the compartment 19, into positions where the threads will extend over the mandreled heads of the bobbins and into positions where the threads will be held by elements l6! and cut by elements actuated by the carriage, the holding of the thread ends continuing after the cutting inasmuch as the cutting takes place below where the threads are being held. As the movement of the carriage continues the bobbins carried by it will be lifted and positioned between the mandreled heads of the spindles and the bobbin pressers then occupying a disengaging position. Thereupon, through the action of its actuating cam 7| the mechanism controlling the bobbin pressers will release them to hold the bobbins in place, the trailing threads then being bound between the ends of the bobbins and the mandreled heads of the spindles so that the threads will wind upon the bobbins when the wind is continued. As soon as the carriage has supplied the spindles with a fresh supply of bobbins it returns to its position of rest beneath the magazines, As it returns it allows the means which holds the trailing threads and shears to resume their normal disengaging positions. The return of the carriage also opens the bottoms 8D to the compartments 79 allowing the wound bobbins to fall out and be disposed of as may be desired. This opening of the bottoms of the compartments is occasioned by the carriage striking the head 83, moving this head into a position where it becomes bound between the pawl |6| and the abutment I60. This marks the completion of the return movement of the carriage, the clutch mechanism then having completed its cycle of rotation, whereupon the cam 56 on the under side of the cam disk 56 will have depressed the lever 5| thereby throwing the control lever again into latched engagement with the fork 4|, and this changed position of the levers again throws the thread guide carriers 25 into threaded engagement with the thread guide rods, and again starts the drive for the spindles and thread guide rods, when the operation is repeated, the cam plate 56 of the clutch mechanism in the meantime being locked in its disengaged position.

The winding machine having now been fully described, it may be pointed out that the invention is in no way limited to the exact embodiment of the single parts as illustrated and described.
